Question

For the light key component, Equilibrium relation is

(a) yK=x

(b) Kx=y

(c) Depend upon trays

(d) Can’t be specified

I have been asked this question by my school principal while I was bunking the class.

I want to ask this question from Key Components of Multi component Distillation topic in division Key Fractionation Concepts of Distillation Design

Answer 1

The correct choice is (a) yK=x

To explain I would say: Here Kx=y is the equilibrium relation, which does not depends upon the number of trays or the vice versa relation i.e.  Kx=y representing x and y moles of gas and fluid.
